Specification of Letters Patent.

Patented May 30, 1916.

Application filed July 6, 1914. Serial No. 849,257.

To all whom it may concern Be it known that I, MICHAEL SMoLENsKY, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have .invented certain new and useful Improvements in Valve Mechanism for Pumps, Compressors, &c., of which the following is a specification.

This invention relates to valve mechanism for pumps, compressors or the like, and embodies an improved valve chest and avalve arrangement therein, said valves controlling ports or passages of novel arrangement or construction.

In the accompanying drawings, the invention is shown applied to hand pumps, but it can be applied to power pumps as well.

In the drawings; Figure 1 is a side elevation of a double-acting pump, showing. the intake side. Fig. 2 is a vertical longitudinal section of the valve chest shown in Fig. 1. Fig. 3 is a partial end view of Fig. 1.

Referring specifically to the drawings, 6 indicates the pump cylinder and 7 the valve chest, which may be made either separate from or integral with the cylinder. In the figures it is shown integral. The piston 8 reciprocates in the cylinder. Communicating with the cylinder at either end (in the double-acting type), are ports 9 and 10 which open into corresponding valve cyl inders 11 and 12, and 13 and 14. The cylinders 11 and 12 are located at an angle to each other, likewise the cylinders 13 and 14, the cylinders 11 and 14L being located in opposite axial alinement, and the cylinders 12 and 13 being located in parallelism, adjacent to each other, so that they stand side by side at or about the middle of the valve casing. This arrangement is convenient for communication with the outlet 29.

Within the respective valve cylinders are piston or sliding plug valves 15, 16, 17 and 18, the ends of which are tapered as indicated at 15', 16', 17 and 18', and adapted to seat against the tapered seats 11, 12, 13 and 1 1 of the respective valve cylinders. By-passes 19, 20, 21 and 22 are respectively provided in connection with the valve cylinders, these by-passes being cored in the valve casing to provide or establish communication around the valves under certain conditions. The valve cylinders are provided with and closed by suitable screw plugs 23, 24, 25 and 26, respectively. These plugs are of cage construction, that is, they have openings communlcatlng w th the lnlet and outlet passages 27 and 29, the inlet 27 bemg branched as indicated at 28, to connect with the opposite inlets at the opposite endsof the casing. The outlet 29 opens from both of the outlet valve chambers, as above described.

In the operation of the double-acting.

pump, the piston moving to the left as shown the arrow in Fig.2 will lift the valve 16 and close the inlet valve 15, the fluid passing through the by-pass 20 and through the openings in the plug 24. to the outlet 29, and at the same time fluid is drawn in through the inlet 22, the valve 18 being drawn to position between the opposite ends of the by-pass 22 and opening the passage through the cage plug 26. The same action closes the valve 17 against its seat, thereby closing the outlet passage 21. On the other stroke, the reverse operation takes place.

One of the advantages of the construction shown and described is that the valve chest (and also cylinder if desired) can be structure, so there is no chance for leaking.

What I claim as new is 1. A double-acting pump comprising a pump cylinder with ports communicating with opposite ends thereof respectively and extending toward the middle thereof, and a valve chest having inlet valve cylinders each of which communicates at its inner' end with one of said ports, and outlet valve cylinders each of which also communicates with one ofsaid ports, and suitable valves in said valve cylinders, said valve cylinders being located in angular relation toeach other, and provided with exteriorly removable closures at their outer ends and also with lateral pipe connections at said ends.

2. A double-acting pump comprising a pump cylinder with ports communicating with opposite ends and extending toward the middle thereof, and a valve chest having in- This results i110 a removable closure at the outer surface *b of the casing.

3. A pump valve mechanism comprising a valve casing having a cylinder therein, and a by-pass communicating at opposite ends with said cylinder, a valve movable in the cylinder and arranged to open or close said by-pass, a hollow plug in the end of the cylinder, said plug having openings communicating With said cylinder to permit flow therethrough into the cylinder, and a lateral inlet pipe to the cylinder communicating With said openings at a distance from the bypass, the valve controlling the passage through said openings and plug to the bypass.

4. A pump valve mechanism comprising a valve casing having a cylinder therein, and a by-pass communicating at opposite ends With said cylinder, a valve movable in the cylinder and arranged to open and close said bypass, a hollow plug in the end of the cylinder, said plug being open at one end to permit fioW axially through the same to or from the cylinder and also having lateral openings for the passage of fluid so flowing, to or from the by-pass.

In testimony whereof, I afix my signature in presence of tWo Witnesses.
